Wonder Woman couldn't originally fly in the comics, although in the 60s I think they gave her the ability to ride air currents or something. She only got the ability to fly properly in the 80s, through typical comic book ********.

the very first couldn't
also fun fact:
early superman couldn't fly either he could just jump impossibly high kind of like the hulk thus the whole "Can leap tall buildings" if you think about this now you are like "Duh, he can fly"
